residential domestic chilled water units

Willfly

I live in a desert climate (daytime temps reach to avg. 105 F daily) and during the 6 months of summer the domestic water enters the house at about 90+ F. Also, the water enters the house at about 80 gpm pressure. I would like to have the water maintain about a 55 F temperature during the summer months. Anyone have any ideas on a solution to my situation?

Drill a deep closed loop well?

Bury the line deeper to where the ground temp is 50* year round.

HVACNUT

Move.

Buy a bunch of drinking fountain/ water coolers, run you water lin through them.

Does it ever freeze there? If not I bet your water pipe is just a few inches below the surface where it absorbs lots of atmospheric heat. And not just yours, but the whole city's. Just burying it deeper in the 50 ft or whatever from the street to your house won't fix that..

This would work but may not have enough capacity. You could dedicate it to 1 sink and would need a storage/buffer tank

The upside is your water heating bill must be low

I don't know if you can find a consumer-grade off-the-shelf solution, but a tube-in-tube heat exchanger, storage tank, refrigeration condenser, and pipes and a pump to connect everything should work. It'd be kind of a Rube Goldberg setup though.

It's an interesting project. What is your water usage like? You'd need to know your average usage, peak usage, min and max incoming temp and of course your design outlet temp to figure out the sizing.

I suspect that this won't be a $400 project.

I assume you are just wanting cold drinking water?
Anything you do will require energy.
Do you have AC in the house?
Do you get any nighttime cooling because of no cloud cover?

Which is why I said dedicate it to one sink. Building a system will not be cost effective

You don't have a water dispenser for the refrigerator?

Couldn't you just have the water go into a tank when it comes in the house before it goes anywhere else? It would cool off to whatever temp the house is over time. If the tank was big enough, you wouldn't have cold water, but the temp would drop down from 90 which is crazy.

Gordy

Better insulate that idea, or the house will end up being heated buy the tank if it's sizable. If you insulate the tank then it won't cool either..

Easiest is to keep a pitcher of water in your refrigerator.Or buy ice.
